In the episode "Dough Ray Me-ow", while the cat Heathcliff can be the nicest, he is very dopey and quite stupid. Such to the point that it can be mind-bogglingly and or ludicrous, from ranging the classic ol 'forgetting how to breath' gag to making obliviously simple-minded mistakes or acts of stupidity that could've gotten himself killed.
